Move namespace logic from app01/02 to common components/ folder

[palladius]

Is there a reason why the namespace part was put in the apps: https://github.com/palladius/clouddeploy-platinum-path/blob/main/apps/app01/k8s/overlays/dev/namespace.yaml
and not consolidated in the base components/ part (https://github.com/palladius/clouddeploy-platinum-path/tree/main/components/common/dev)?

I don't see a reason to do this within apps instead of on component-level. And I would strongly recommend lifting this into component like you are proposing. 👍
